Snake Rewind: Building a Retro Snake Game in C with Raylib

Currently Playing: Visual Glitchcraft: Snake Through a Broken Display [Snake Rewind Ep 8]

🧙‍♂️ In Episode 8 of *Snake Rewind* we go full visual glitchcraft: layering on a suite of postprocessing effects to give the game that worn out CRT look with a modern shader twist. From retro scanlines and flickering to color channel separation and screen distortion, this episode is all about *style*. We transform our clean pixel grid into something that feels alive, unstable and beautifully broken. 🎮 What we cover: - Adding scanlines with customizable frequency and opacity - Creating a time based flicker effect for a subtle CRT shimmer - Simulating image distortion using sine waves - Splitting RGB channels with a chromatic aberration shader - Combining all effects into a clean shader pass pipeline This is the moment where Snake Rewind steps fully into arcade mode. 📺 Full Snake Rewind Series Playlist: https://www.youtube.com/playlist?list=PLI7p1zrAYQeUb67kPtsyduLk1aJChzIQZ 📖 Companion Blog Post: https://letsreinventthewheel.github.io/blog/snake-rewind-ep8/ 🧠 Source code: https://github.com/letsreinventthewheel/snake-rewind Snake Rewind isn't just a remake. It is Snake with a twist: - 🐍 Clone snakes that retrace your path - ✨ Retro shaders: bloom, scanlines, chromasep - 🎮 Reactive UI, game feel, and juicy feedback - 🎧 Music and SFX polish (hopefully we can find free sounds) 💬 Got questions?
